1-19. (canceled)
A pressure sensitive adhesive composition comprising a poly(phenyleneoxide)-grafted (meth)acrylate copolymer.
- wherein the copolymer is of the formula:
- ˜[MEster]a-[MPPO]b-[Macid]c-[Mpolar]d˜, wherein
- [MEster] represents (meth)acrylate ester monomer units wherein subscript a is 80-99.9 parts by weight;
- [MPPO] represents poly(phenyleneoxide) functional monomer units wherein subscript b is 0.1-10 parts by weight;
- [Macid] represents acid functional monomer units wherein subscript c is 0-15 parts by weight;
- [Mpolar] represents non-acid-functional polar monomer units wherein subscript d is 0 to 10 parts by weight;
- wherein the sum of a to d is 100 parts by weight.
